<br />Where: V=maximum peak particle velocity(inches per second) <br />K= ground transmissivity constant <br />R= distance to structure, (ft) <br />W=maximum pounds of explosive per delay period <br />To determine the distances from the blasts to the various structures, the site plan <br />I ~ developed during our site visit was correlated with the figure provided in the Lyman and Henn <br />work. <br />rl <br />The results aze summarized in Table I. Particle velocities ranged from .088 inches per <br />second at the NPW storage tank to 0.606 inches per second at the solids and control buildings <br />for the quarry (Q) blasts. Particle velocities ranged from 0.227 inches per second at the NPW <br />storage tank to 3.628 inches per second at the solids building for the production (P) blasts. <br />Particle velocities ranged from 0.198 inches per second to 1.490 inches per second at the <br />control building for the access road (A) blasts. <br />LJ The particle velocities were estimated for the lighting facilities and aze summarized in Table II. <br />Particle velocities of 4.00 inches per second for the (Q) blasts and 47.649 inches per second for <br />the (P) and (A) blasts were estimated. <br />CONCLUSIONS/RECOMMENDATIONS <br />Our analyses indicated similaz results to the analyses performed by Lyman and Henn. <br />The major difference being that we had access to the wastewater treatment facility and were <br />able to detemune the distances to the various structures. Lyman and Henn and the State of <br />Colorado both used a particle velocity of 0.75 inches per second as the limiting velocity. As can <br />4 <br />
